all 4 in parallel. Thats with no dimmer so running full bore on a 320H-C2800b

2800/4= 700mA
54v x 700mA = 37.8w each
37.8w x 4QB = 151w total
Looks like you aren't using that driver up to its potential. Usi g 363w to get 151w in output.

Robin did mention, a while back, that the next batch may be priced lower, FWIW.

Sorry board prices will be same for next batch as long as they are S6. The batch after that could see a price drop.
Prices of heatsinks will drop before prices of boards drops

Which way is the best way to go under a budget to beat a 1000 Watt HPS Single End.

1. 5 QB board set up. 4 square with #5 in the middle. 4 board in a square. Each QB about 16" apart??

2. 4 QB board set up and 3 Citizen 1212 COBs in the middle. Stephen/Robin have 1212's for $15
